I watched a few of the emulator videos at the top and theirs run super fast. Then I watched some at the bottom, and theirs run similar to mine, where after completely a level, the ability to select in the menu is super slow. You have to wait for the menu to finish its wiggle animation before you can select a different level. Does anyone know why this is happening, and how people at the top do not have this issue? I have tried 2 different emus to see if it was the emulator I was using, and both are the same.

Actually, is not an EMU problem. You just need to spam the START button to make the wiggler animations WAY faster. My suggestion is to press START 3 times very fast, then move right and press START again. Hope this helps...
